Research On The Strength And Conditioning Status Of Male Youth Football Players In Beijing Sport University And Establishment Of The Evaluation Criteria

Objective:Through the physical fitness test,the author had a comprehensive understanding of the physical fitness status and characteristics of male youth football athletes in Beijing Sport University,and therefore established the evaluation criteria for the physical fitness test of youth football players,providing theoretical basis and data support for the physical fitness training of youth football players.Methods:This study mainly used test method,questionnaire survey method and mathematical statistics method.In this study,458 male football youth athletes aged 12 to 18 from Qinhuangdao China Football Sports Academy took the physical fitness test,which enabled the author to understand the physical fitness status and characteristics of male youth football athletes in Beijing Sport University.The evaluation criteria for the physical fitness test of youth football players in Beijing Sport University was established as the weight of each test index was determined by questionnaire survey method.This study used the one way ANOVA to explore the physical features of athletes in different positions.Then,used the percentile method to establish the evaluation criteria.Finally,used the consistency test method to test the criteria.Results:1.The physical fitness of male youth football players in different positions was quite different.(1)In standing long jump,the performance of the goalkeepers was significantly lower than that of the midfielders(P<0.05);the performance of defenders was significantly lower than that of midfielders and strikers(P<0.01);the performance of midfielders was significantly higher than that of strikers(P<0.05).(2)In vertical jump,the performance of defenders was significantly lower than that of midfielders and strikers(P<0.01).(3)In pull-ups,the performance of defenders was significantly lower than that of midfielders and strikers(P<0.01).(4)In exhausted push-ups,the performance of the goalkeepers was significantly lower than that of the midfielders(P<0.05);the performance of midfielders was significantly higher than that of defenders and strikers(P<0.01).(5)In exhausted bent leg sit-ups,the performance of goalkeepers was significantly lower than that of defenders and midfielders(P<0.01);the performance of the defenders was significantly higher than that of the strikers(P<0.05).(6)In 30m sprint running,the performance of the goalkeepers was significantly higher than that of the defenders(P<0.05);the performance of defenders was significantly lower than that of midfielders and strikers(P<0.01).(7)In T-run test,the performance of the goalkeepers was significantly higher than that of the defenders(P<0.05);the performance of defenders was significantly lower than that of midfielders and strikers(P<0.01).(8)In sit and reach test,the performance of midfielders was significantly higher than that of defenders and strikers(P<0.05).(9)In the 1.5 mile race,the performance of the strikers was significantly higher than that of the defenders(P<0.05).2.The physical fitness evaluation criteria for male youth football training players aged 12 to 18 from Beijing Sport University was established.The Kappa value was 0.788,P<0.001.Conclusions:1.There was a certain gap between football youth athletes from Beijing Sport University and athletes from foreign countries in terms of the explosive power of lower limbs and aerobic endurance.2.There were physical fitness differences among youth football players in different positions on the field.Strikers had better performance in speed and aerobic endurance.Midfield athletes had better performance in explosive power of lower limbs,upper limbs endurance and agility.Defender athletes had better performance in abdominal muscle endurance.And goalkeepers had better performance in agility and flexibility.3.According to the score of individual physical fitness test and the weight of test indexes,the comprehensive physical fitness evaluation criteria of five-categories could really make an accurate evaluation on the physical fitness of male youth football players.
